correns described that the inheritance of variegated color on the leaves of certain plants was determined by the maternal parent only. what phenomenon does this describe?
Answers
The phenomenon in which the inheritance of variegated color on the leaves of certain plants was determined by the maternal parent only describes B) chloroplast inheritance.
Structures such as the chloroplast and mitochondria contain their own DNA.
Evolutionary studies predict that structures such as chloroplast and mitochondria were first smaller living organisms that were engulfed by larger organisms hence these cells have their own DNA.
The chloroplast DNA which is not present elsewhere in a plant is inherited by the daughter plant from the mother plant only i.e maternal inheritance. Hence, as the variegated color was inherited from the maternal parent, it depicts chloroplast inheritance.
Although a part of your question is missing, you might be referring to this question:

A Punnett square tracks inherited traits, and a pedigree chart is used to predict the genotype of offspring.
A pedigree chart predicts the percentage of offspring that will have a specific trait, and a Punnett square tracks which organisms are carriers for a specific trait.
A Punnett square tracks family traits, and a pedigree chart identifies the phenotype of the organism.
Answers
The probability of offspring having wrinkled seeds in the given cross between a pea plant with round seeds (Rr) and a pea plant with wrinkled seeds (rr) is 0%. is A. A pedigree chart tracks inherited traits, and a Punnett square is used to predict the genotype of offspring.
When a pea plant with round seeds (Rr) is crossbred with another pea plant with wrinkled seeds (rr), the probability of offspring having wrinkled seeds is 50%. This is because the round seed trait is dominant (R) and the wrinkled seed trait is recessive (r).
In the given cross, the round-seeded parent contributes one dominant allele (R) and the wrinkled-seeded parent contributes one recessive allele (r). The possible genotypes of the offspring are Rr and rr. The genotype Rr would result in round seeds, while the genotype rr would result in wrinkled seeds. Since there is one rr genotype out of the two possible genotypes, the probability of offspring having wrinkled seeds is 1 out of 2, or 50%.
The true statement is: A Punnett square tracks inherited traits, and a pedigree chart is used to predict the genotype of offspring. A Punnett square is a tool used to determine the possible genotypes and phenotypes of offspring based on the genotypes of the parents, while a pedigree chart is a visual representation of the inheritance patterns of traits across generations. Therefore, Option A is correct.

Answers
RNA polymerase II by itself does not have a strong affinity for binding DNA due to the requirement of general transcription factors to bind RNA polymerase II to the DNA molecule gives the cell more precise control over transcription (Option D).
What is RNA polymerase II?RNA polymerase II is an enzyme that catalyzes the synthesis of messenger RNA or mRNA during trasncription, which is then used as a template to generate a protein during the process of translation.
RNA polymerase II does not exhibit a strong affinity for binding DNA because this protein binds to different factors during transcription, thereby enhancing the affinity of the protein-DNA interaction during specific stages of the process.
Therefore, with this data, we can see that RNA polymerase II does not exhibit a strong affinity for DNA but it triggers transcription by binding other factors during this process.
Complete question:
RNA Polymerase II by itself does not have a strong affinity for binding DNA. Select the explanation that describes why cells do not need for RNA polymerase II to have a strong affinity for binding DNA for transcription to occur.
A) RNA Polymerase II always works in tandem with RNA Polymerase I or III so that it is not required to have a strong affinity for binding to DNA.
B) Natural selection has not yet had time to work sufficiently to produce an RNA Polymerase that has a strong affinity for binding DNA.
C) RNA Polymerase II binds to the sigma factor, which facilitates its binding to DNA.
D) The requirement of general transcription factors to bind RNA polymerase II to the DNA molecule gives the cell more precise control over transcription.
E) RNA Polymerase II tightly binds to RNA, it is not required to bind to DNA to properly carry out its functions.

It increases the chance of meiosis to acquire desirable traits.
It increases the chances that a fraction of the offspring will survive into adulthood.
It increases the offspring ability to compete for limited resources. It increases the probability of genetic drift.
Answers
The ability of bluefin tuna to produce 10 million eggs per year can increase their fitness in several ways. the correct answer is b) It increases the chances that a fraction of the offspring will survive into adulthood.
Producing a large number of eggs can also increase the genetic diversity of the population, which can be beneficial for the species long-term survival. This genetic diversity arises from the higher probability of meiosis generating desirable traits in a larger pool of potential offspring.
One of the main advantages is that it increases the probability that at least some of the offspring will survive to adulthood, as there are more opportunities for the eggs to be fertilized and develop into viable embryos.
Therefore, the answer is B).

a blood cell has a diameter that is 8 cm long. under a microscope, it looks 64000 cm long. what magnification acale was used
Answers
The magnification scale used for a blood cell with a diameter of 8 cm that appears 64,000 cm long under a microscope can be calculated using the formula for magnification.
Magnification = Image size/ Object size
So, Magnification = 64,000 cm/ 8 cm = 8,000.
The magnification scale used for the observation of the blood cell was 8,000. The image of the blood cell appears 8,000 times larger under the microscope than its actual size.Blood cells have a diameter of about 7.5 micrometers, which is equal to 0.00075 cm. Therefore, an 8 cm blood cell would be abnormal and not possible.
The question may have a typo in the diameter measurement. Regardless, the magnification scale calculation remains the same, which is equal to 8,000.
